AMERICAN COLEOrTEUA. 305 



ina many pciints in tlic description by Candeze. not fitting; the speci- 

 lueus bofbro mc I gave our species a name. Tiirough the kindness of 

 Dr. Candiize, I have been enabled to compare the two species. The 

 European form is more robust, broader and less shining, the thorax is 

 as wide as long, and more constricted at base than apex. The elytra 

 are nut or barely twice as long as wide and the intervals scarcely 

 convex. There is also no asneous tinge to the surface. 



Specimens occur in Pennsylvania, and more abundantly, although 

 not commonly in the District of Columbia (Ulke). 



In general aspect our species recalls the form of Jlorisfonotus trans- 

 fuguit, Lcc. 



C. dabius. n. sp. — Brown, sub-opaque, oblong, moderately depressed, sparse]}' 

 clothed with short cinereous pubescence. Head finely granulose. Antennaj 

 brownish, pale yellow at base. Thorax not longer than wide, finely granulose 

 and more shining at base, median line smoother and subcarinate, sides parallel 

 behind, slightly rounded and somewhat narrowed in front; hind angles testa- 

 taceous, short, acute at tip and carinate, carina rather distant from margin and 

 one-third the length of thorax. Elytra short, twice the length of thorax, and 

 as wide as base, sides nearly parallel and obtusely rounded at apex, moderately 

 convex; surface striate, strife punctured, intervals flat densely granulose. 

 Body beneath piceous, sparsely jmuctured legs testaceous. Length .10 — .12 

 inch ; 2.5 — 3 mm. 



In one specimen before me the basal margin of the elytra is nar- 

 rowly testaceous, also the suture near the apex and the apical margin 

 of the last abdominal segment. This species is from the description 

 closely allied to dermestoklcs, of Europe, and to our own s>trlatulus, but 

 is more convex and less opaque and smaller than the latter. 



'J'wo specimens are before me from Nebraska and Dacota, from the 

 cabinet of ^Ir. Ulke. 



C. colon, n. sp. — Black, opaque, sparsely clothed with silvery pubescence. 

 Head convex, granulately jiunctured. Antennte black, not as long as the head 

 and thorax. Thorax slightly longer than wide, narrower at ape.x than at base 

 sides moderately arcuate, hind angles acute, divergent, not prolonged, with an 

 acute carina extending nearly half the length of the thorax; surface convex 

 opaque granulately punctured and with the median carina distinctly elevated. 

 Elytra sligiitly broader than thorax and twice as long, feebly convex, black, 

 o[>aque with a yellow spot on each at the apical third; surface striate, striie 

 punctured, intervals flat punctulate and finely rugose. Body beneath densely 

 punctured. Legs black, tarsi piceous. Length .16 inch ; 4 mm. 



This species is scarcely more convex than atriahilus, which it resem- 

 bles in general aspect, differing notably in the carinate thorax and cly- 

 tral spot. From the dark varieties oiornatus, it differs in being much 

 less convex, less shining and with flat elytral intervals and by the two 

 sub apical spots.
